Description

Technical Field

[0001] The invention relates to the technical field of FPSO, and in particular to an FPSO upper module with an integrated pipe gallery and a layout method thereof. Background Art

[0002] Floating production storage and offloading vessels (FPSO) are key facilities for offshore oil development. They receive oil, gas and water mixtures from oil wells through submarine pipelines, store qualified crude oil or natural gas in the ship's cabin after processing, and transport them to land or other destinations through shuttle tankers or pipelines when a certain amount is stored. They are mainly used for the exploitation, processing, storage and transportation of offshore oil, natural gas and other energy sources. FPSO has the following characteristics:

[0003] Strong adaptability: It can work in a wide range of water depth conditions, from shallow water to deep water.

[0004] High efficiency: It has efficient oil and gas processing capabilities and can process large amounts of crude oil and natural gas.

[0005] Strong oil storage capacity: It can store large amounts of crude oil and reduce dependence on submarine pipelines.

[0006] Good mobility: Compared with fixed platforms, FPSO can be moved more easily and is suitable for the development of different oil fields.

[0007] Strong ability to resist wind and waves: The design takes into account the impact of harsh marine environment and can withstand strong winds and waves.

[0008] FPSO is usually composed of a lower hull and an upper module. The lower hull provides buoyancy and oil and gas storage, while the upper module is used for oil and gas extraction and processing. Each module is connected via a common pipe gallery module to form a whole ship system. The upper module and pipe gallery of FPSO are usually set up separately. After the modules and pipe gallery are built, they are hoisted to the upper part of the FPSO hull by floating cranes or gantry cranes for integration. After each module and pipe gallery are in place, the pipelines and cables between the modules and the pipe gallery can be connected. The workload of hoisting integration and in-place connection is huge. At the same time, since the module pipe gallery is set up separately, it is necessary to set up columns, legs and corresponding beam grid structures separately, and the amount of steel processing and the weight of the whole FPSO ship are also increased. On the other hand, most of the pipelines of FPSO are directly fixed on the pipe gallery by buckles. When the FPSO swings with the waves and drives the pipe gallery to shake, the pipeline and the pipe gallery do not have the ability to slide relative to each other, and cannot offset the pulling of the pipe gallery on the pipeline, which is easy to cause deformation or even damage of the pipeline.

The position of the common side beam 15 of the module horizontal layer and the layout requirements of pipelines and cables are comprehensively considered to determine the position of the pipe gallery layer 16; Step 3: Unscrew the bolts in the outer screw hole 34 and the inner screw hole 23 respectively, remove the upper outer connecting part 4 from the lower outer connecting part 3, and remove the upper inner connecting part 5 from the lower inner connecting part 2; Step 4: clamp the lower inner connecting part 2 under the pipeline in the pipe gallery 12, clamp the upper inner connecting part 5 above the pipeline, and align the inner screw holes 23 of the two, insert the bolts into the inner screw holes 23 and tighten them, fix the upper inner connecting part 5 and the lower inner connecting part 2 together, and clamp the pipeline in the middle; Step 5: Pick up the inner connecting part, insert the stopper 26 at one end below it into the arc groove 324, and then insert the stopper 26 at the other end below the inner connecting part into the corresponding arc groove 324, so that the lower inner connecting part 2 is located in the corresponding lower outer connecting part 3; Step 6: According to the method of step 5, install the upper inner connecting part 5 in the upper outer connecting part 4. At this time, the outer screw holes 34 of the upper outer connecting part 4 and the lower outer connecting part 3 are aligned one by one, and the bolts are respectively inserted into the outer screw holes 34 and tightened to fix the upper outer connecting part 4 and the lower outer connecting part 3 together, and the inner connecting part is wrapped; Step 7: Repeat the above steps and fix all pipes on the pipe gallery layer 16 with the connecting parts.

[0034] The pipe gallery 12 and the upper module 11 are connected by common columns 13, common legs 14 and common side beams 15 to reduce the amount of steel used and the weight of the hoisting. The upper module 11 body is arranged on the side of the FPSO close to the ship, and the pipe gallery 12 is arranged on the side close to the midship to reduce the impact of the hull shaking on the pipe gallery 12 and the pipelines, and at the same time it is beneficial to the connection of pipelines and cables between other modules. The pipe gallery layering 16 comprehensively considers the position of the common side beams 15 of the module horizontal layer and the requirements for the layout of pipelines and cables, which can further reduce the amount of steel used and the weight of the pipe gallery 12.

[0035] Unscrew the bolts in the outer screw hole 34 and the inner screw hole 23 respectively, remove the upper outer connection part 4 from the lower outer connection part 3, remove the upper inner connection part 5 from the lower inner connection part 2, clamp the lower inner connection part 2 under the pipeline in the pipe gallery 12, clamp the upper inner connection part 5 above the pipeline, and align the inner screw holes 23 of the two, insert the bolts into the inner screw holes 23 and tighten them, fix the upper inner connection part 5 and the lower inner connection part 2 together to form an inner connection part, and clamp the pipeline in the middle; pick up the inner connection part, insert the limit block 26 at one end below it into the arc groove 324, and squeeze it into the arc groove 324, so that the first spring 25 is compressed and contracts, so that the inner connection part The length of the connection part is smaller than that of the outer connection part, and then the limit block 26 at the other end below the inner connection part is inserted into the corresponding arc groove 324, and the inner connection part is loosened. The first spring 25 rebounds and pushes the limit block 26 into the corresponding arc groove 324, so that the lower inner connection part 2 is located in the corresponding lower outer connection part 3. According to the same method, the upper inner connection part 5 is installed in the upper outer connection part 4. At this time, the outer screw holes 34 of the upper outer connection part 4 and the lower outer connection part 3 are aligned one by one, and the bolts are respectively inserted into the outer screw holes 34 and tightened to fix the upper outer connection part 4 and the lower outer connection part 3 together, and the inner connection part is wrapped up. When the hull shakes left and right, the outer connection part The inner connection part is dragged by the pipe gallery 16 and tends to maintain its original state, so that the outer connection part and the inner connection part rotate, and the ball 242 rolls on the inner surface of the outer connection part to reduce the rotation amplitude of the inner connection part, thereby ensuring that the pipe is fixed and preventing the inner connection part from rotating too much and breaking the pipe; since there are many pipes and they are arranged at different parts of the hull, the outer connection part and the inner connection part at some parts cannot rotate coaxially, and there will be traction between the two, which compresses the buffer part 24, compresses the second spring 246, and the inner column 244 retracts into the outer column 245, reducing the distance between the outer connection part and the inner connection part. The length of the pipeline being pulled is reduced to prevent the pipeline from being broken; when the hull shakes back and forth, the outer connection part shakes with the hull, and the inner connection part tends to maintain its original state due to the pulling of the pipeline, and moves relative to the outer connection part. The ball 242 rolls on the inner surface of the outer connection part to reduce the amplitude of movement of the inner connection part, ensuring that the pipeline is fixed while avoiding excessive movement of the inner connection part to break the pipeline. The arc rib 323 squeezes the limit block 26 to shrink the first spring 25, reducing the collision force between the inner connection part and the outer connection part, preventing the top cover part 32 from being damaged, losing the restriction on the inner connection part, causing damage to the connection part, and losing the buffering effect on the pipeline.

Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention.
